Krix KA-1100 Subwoofer Amplifier

The KA-1100 Subwoofer Amplifier by Krix is a powerful and precision-engineered solution designed to unlock the full potential of passive home-cinema subwoofers. Developed completely in-house, the KA-1100 combines advanced Class-D ICEpower™ amplification, intelligent DSP processing, and a robust dual-mono architecture to deliver deep, controlled, and cinematic bass performance.

Purpose-built for Krix’s premium passive subwoofers — including the MX-5, MX-10, Cyclonix 11, and Cyclonix 12 — the amplifier ensures that every low-frequency detail in movie soundtracks and music is reproduced with maximum impact and minimal distortion. Its integrated DSP modes are pre-configured to perfectly match these subwoofers, allowing the amplifier to extract the best possible performance while maintaining full dynamic range and protecting the drivers.

Beyond raw power, the KA-1100 is designed with real home-cinema environments in mind. The fan-less architecture guarantees silent operation, ensuring the amplifier never distracts from quiet scenes or subtle audio moments. With professional connectivity options, rack-mount capability, and an elegant brushed aluminium design, the KA-1100 integrates seamlessly into both dedicated cinema rooms and stylish living-room systems.

For enthusiasts who demand clean, powerful bass and reliable performance, the KA-1100 represents a carefully engineered amplifier that elevates the entire home theatre experience.

Dual-Mono Amplification for Massive Bass Performance

The KA-1100 delivers up to 700W RMS per channel at 4 ohms, providing the power required to drive demanding passive subwoofers with authority. Its dual-mono architecture ensures each channel operates independently, improving channel separation, stability, and power delivery.

This design allows the amplifier to produce deep, room-filling bass with exceptional control, ensuring explosive movie scenes and musical low frequencies remain tight, impactful, and distortion-free even at high listening levels.

Custom DSP Modes Optimised for Krix Subwoofers

A major advantage of the KA-1100 is its built-in DSP processing with pre-configured modes specifically tuned for MX-5, MX-10, Cyclonix 11, and Cyclonix 12 subwoofers. These presets optimise crossover points, power limits, and filtering to extract the best performance from each model.

By automatically applying the correct processing, the amplifier ensures maximum output without compression, preserving the dynamic energy of movie soundtracks while maintaining accurate and balanced bass reproduction.

Advanced ICEpower™ Class-D Amplification Technology

The KA-1100 uses ICEpower™ Class-D amplification, a technology known for delivering high efficiency, excellent power output, and extremely low distortion. This modern amplifier design produces clean and accurate bass while generating minimal heat.

Combined with the custom 24-bit DSP signal processor, the KA-1100 maintains impressive audio fidelity with THD+N as low as 0.001%, ensuring every low-frequency detail remains precise and powerful.

Intelligent Protection with Soft Limiting

To protect both the amplifier and the connected subwoofer, the KA-1100 incorporates soft limiting technology. If an input signal exceeds the maximum capacity of the subwoofer, the amplifier automatically reduces output smoothly instead of clipping.

This prevents distortion and protects the loudspeaker driver from damage, allowing users to enjoy high-impact bass at loud volumes with confidence and reliability.

Silent Fan-less Design for Dedicated Home Cinemas

Unlike many powerful amplifiers that rely on cooling fans, the KA-1100 uses a fan-less design that ensures completely silent operation. This is particularly important in home theatre environments where background noise can distract from quiet scenes.

The absence of mechanical noise means the amplifier remains acoustically invisible, allowing listeners to fully immerse themselves in the cinematic experience.

Flexible Integration and Professional Connectivity

The KA-1100 is built for easy integration into a variety of home theatre systems. It supports both balanced and unbalanced inputs, making it compatible with professional processors and consumer AV receivers.

Additional features like a 12V trigger for automatic power control, rack-mount ears for AV racks, and a sleek removable aluminium fascia ensure the amplifier can be installed cleanly in dedicated cinema racks or hidden within cabinetry.
